This species looks quite similar to C. indica, but differs by the persistence of its floral bracts, its somewhat longer, tuberculate pedicels (especially in fruit), and its preference for high altitudes.

Canna flaccida has often been confused with C. glauca. It clearly differs from that species, however, by having reflexed petals and much larger and wider free parts of staminodes.

Canna indica is different from C. jaegeriana. The latter occurs at high altitudes and has larger leaves than C. indica. Canna jaegeriana has orange flowers with a curved tube, all staminodes with erect free parts, ellipsoid seeds, and caducous bracts. Moreover, in C. jaegeriana the lower side of the leaves, the sheaths, and parts of the inflorescence are always lanuginose.

Canna indica is different from C. tuerckheimii. The latter occurs also at high altitudes and has also larger leaves than C. indica. Canna tuerckheimii is characterized by orange-red flowers with a straight floral tube, staminodes with patent free parts, subglobose seeds, caducous bracts, and a more or less lanuginose lower side of the leaves, as well as a glaucous inflorescence.

By the above-mentioned characters C. jaegeriana differs from C. tuerckheimii which has orange-red, straight flowers with free part of staminodes patent, subglobose seeds, and which occurs in Central and western South America, also at high altitudes. Both species have a more or less lanuginose lower side of the leaves.

Some specimens from high places in South America are difficult to identify. Because of cultivation, plants may be larger and may have larger leaves suggesting C. jaegeriana, while the flowers are like those of C. indica. There could also be hybrids involved.

Some specimens are aberrant by having large, subglobose seeds of 9–10 by 8–9 mm. It concerns specimens from high altitudes in Ecuador (Pichincha and Cotopaxi) and Bolivia (Tarija).

Part of the specimens from Puerto Rico, Haïti, and the Dominican Republic is slightly different by small and caducous floral bracts, small sepals (c. 0.5 cm long), and red flowers with petals shorter than the staminodes (see C. pertusa and C. domingensis).

Canna bangii, the other species from high places in the Andes, has 1 recurved staminode at anthesis, and the free part of the other staminodes are longer than those of C. tuerckheimii.

Canna jaegeriana differs from C. tuerckheimii by purely orange flowers with the floral tube curved around the middle and the free part of the staminodes erect (versus orange-red straight flowers with free part of staminodes patent), and by ellipsoid (versus globose) seeds.

Some specimens of C. tuerckheimii from high places in the Andes are difficult to identify. Because of cultivation plants may be larger and may have larger leaves suggesting C. tuerckheimii, while the flowers are like those of C. indica. There could also be hybrids involved here.
